The arrival of summer is eagerly anticipated each year, marking a time for longer days, warmer weather, and outdoor adventures. But exactly when does summer begin? It's not as simple as flipping a calendar to a specific date. The official start of summer depends on which definition you're using: meteorological or astronomical.

Meteorological Summer vs. Astronomical Summer

There are two main ways to define the start of summer:

Meteorological Summer

Meteorologists prefer a simpler system based on the calendar. For them, summer always begins on June 1st and ends on August 31st. This method provides consistent three-month seasons, making it easier for tracking weather patterns and climate data throughout the year. So, meteorologically speaking, summer 2025 starts on June 1st, 2025.

Astronomical Summer

The astronomical definition of summer is tied to the Earth's orbit around the sun. This is the summer solstice, the day with the longest period of daylight in the Northern Hemisphere. The date of the summer solstice varies slightly each year, falling between June 20th and June 22nd.

Therefore, in 2025, the astronomical start of summer will be on June 20th or 21st, 2025. To know the precise date for your location, you'll need to consult an astronomical calendar specific to your region, as the exact time of the solstice varies based on longitude.

Which Definition Should You Use?

The best definition to use depends on your needs. If you're tracking weather trends or planning seasonal activities based on consistent calendar dates, the meteorological definition (June 1st) is convenient. If you're interested in the precise moment of the longest day and the astronomical event marking the beginning of summer, then use the astronomical definition (June 20th or 21st, 2025).

Summer Solstice Traditions and Celebrations

The summer solstice is often celebrated around the world with various traditions and festivals. These celebrations often revolve around themes of light, fertility, and the renewal of nature. Some examples include:

• Stonehenge, England: Thousands gather at Stonehenge to witness the sunrise on the solstice.
• Midsummer in Sweden: Celebrated with bonfires, maypole dancing, and traditional food.
• Litha (Wicca): A Pagan holiday celebrating the sun's power and abundance.

No matter which definition you prefer, the arrival of summer is a time for joy and celebration. So, mark your calendars for either June 1st or June 20th/21st, 2025, and prepare for the warmest time of the year!
